SPECIFICATION forming part of Letters Patent No. 337,049, dated March 2, 1886.

Application filed December 16, i885. Serial No. 185,850. (No model.)

To all whom it may concern:

Be it known that I, JOS MANUEL DE AGUIRRE Y LIzAoLA, a subj eet ofthe King of Spain, residing at Bilbao, in the Kingdom of Spain, have invented new and useful Im provements in Lifts or Hoists, of which the following is a specification.

This invention relates to an improved lift or hoist, suitable also as a fire-escape.

The improved apparatus has for its object tn effect a rapid raising or lowering to or from a great height.

The essential features of the apparatus are as follows: first, a tirin supporting-pointin the ground, which is obtained by an apparatus which establishes the level and by lateral struts, and, secondly,l by an arrangement of jointed rods or bands which may be extended vertically.

In order to enable the invention to be fully understood, I will describe the same by reference tothe accompanying drawings,in which- Figure 1 is a section on line A B of Fig. 3. Fig. 2 is a section ou line C D of Fig. 3. Fig. 3 is a plan. Fig. 4 shows the apparatus in its working position as applied to a house; and Fig. is an elevation ofthe apparatus, showing the working ot' thejointed rods or bands. The apparatus is constructed of an iron carriage, D, mounted on four wheels, E, the axletrees ot' which are fixed and form part of the frame-work. On this carriage are three series ofjointed bands or rods, F, of. iron or other suitable metal, placed parallel with each other, to sustain between them a plane surface or floor having a balustrade or iron railing, G. Two parallel sides of this iron railing are movable, and are so arranged that they can be applied to any kind of balcony, and serve as a ladder to facilitate access to the upper platform of the apparatus from the house, as will be seen by reference to H, Fig. et.

The movement of the bands P is produced by means of an arrangment of toothed wheels, I, placed in the interior of the carriage and in its rear half, some of which arespur-wheels and somebevel-wheels, for changing the movenient. This arrangement of toothed wheels actuates three screws, J, placed vertically at the middle of the carriage. Each screw J works in a nut, K, to which are adapted rods L, jointed at their ends M with the arms N of tlicjointedbands P. (Shown at Fig. l.) The bands of the three series which correspond with each other are reunited by means of cross-pieces formed of iron rods placed in tubs O, Fig. 2, in order to maintain an equal distance between the jointed bands P.

When the apparatus is folded up, as shown at Fig. 1, the nuts K are at the upper part of the screws. When movement is imparted to them by means ofthe arrangement of toothed wheels above described, the nuts descend, and as they are connected to the outermost arms of the rods they force the latter to unfold or to become extended, and consequently raise the platform. Vhen the nuts K have arrived at the end of their course, the jointed bandsP have reached the extent of their travel, and the platform G is then at an altitude oftwenty meters, which isya height more than snflicient in most cases. A

y The platform G can be placed and stopped at any desired height, as it depends on the spreading out of the rods, and consequently on the number of revolutions of the rst pin` ion of the arrangement of wheels above described.

The apparatus is also provided with waterpipes Q, having the necessary connections or unions placed within the jointed bands, so that it is merely necessary, when the apparatus has arrived at the place where it is to be used, to connect the pipes with the water-supply and to give the water the required direction from the platform, raised to asuitable height.

For the purpose of facilitating the rapidity of the operations, the carriage is provided with receptacles for pipes, cranks, and other accessories for use at fires, two doors on each side of the carriage being provided to allow the pipes hanging from the platform to pass ont.

In order to give greater stability to the apparatus, it is provided with two cables, R, hooked to the two sides of the upper platform, and which pass over two pulleys, S, and are coiled on two cylinders, T, placed on one of the axes of the arrangement of toothed wheels. The apparatus is also provided with two struts, V, placed at the sides of the carriage, as shown in Fig. 4.

As the streets of a town are not generally level, it is necessary to provide the apparatus' with four hand-screws or sorewjacks, X,placed on the axes of the wheels, which allow of the apparatus being kept on a level position,even when the gradient is fifteen in one hundred. To ascertaiuthis level two spirit-levels are provided within the apparatus,placed perpendicularly to each other.

To facilitate access to the upper platform, the apparatus is provided at the rear portion of the frame of the carriage with an iron ladder, H, Fig. 4, which can be folded up in the said frame when not required for use.

The apparatus having arrived at the scene of the lire, the wheels are wedged up, the screw-jacks operated to make the apparatus level, and the struts are placed in position. The apparatus is then raised by mea-ns of cranks placed ont-he axes Nos. l, 2, or 3, Fig. l, according as it may be wished to raise the apparatus more or less` quickly. The platform being raised, the cables are tightened to firmly fix the apparatus, the pipes arejoined, and the firemen can commence to Work.

Itis obvious thatthe apparatus may be modified by changing the materials which compose the parts. Instead of threeseries of jointed bands, two, four, or more series can be eml ployed.

VOther mechanism than that of the toothed wheels represented in the drawings can be employed to effect the elevation of the plat form. Any suitable motive power can be used for this purpose. A telephone or other signal can be employed as a means of communication betweenthe persons on the platform and thoseremainingbelow. Signal'lightsmay be provided above. The platform may beenveloped wholly or partly with metallic cloth as a shelterfrom the flames.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed,

`I declare that what I claim is- The improved lift or hoist above described, and consisting ofa carriage mounted on wheels, which allow of it being fixed level on the ground by means of screw-jacks and struts.

`providedwith al1-arrangement of toothed wheels which actuate screws, by means of which jointed bands or rods can be extended or folded up, the rods raising or lowering a movable platform firmly maintained by means of cords, and carrying water-pipes and other accessories, for the purpose of reselling persons, furniture, and goods, as-described.
